Hi guys,

Something is up with forum's notification system, I'll investigate whats going on. Basically I didn't get the new post notifications and as such didn't know of this post, my apologies.

I'm looking at the sources for the Closed and KnotCount methods and it doesn't do anything that would alter behaviour thats otherwise there in 3dsmax:

int Spline3D::Closed::get()
{
    return (int)( (::Spline3D&)unmanaged() ).Closed();
}

int Spline3D::KnotCount::get()
{
    return (int)( (::Spline3D&)unmanaged() ).KnotCount();
}

In the unmanaged SDK the two calls appear as follows:

int Spline3D::Closed()
{ return (flags & SPLINE_CLOSED) ? 1:0; }

int Spline3D::KnotCount()
{ return knotCount; }

I don't see anything that'd alter the class in any way here.

Does this happen even if you just create a very trivial Spline3D instance (i.e. with one or two knots), or does this only apply to specific cases? I can try to reproduce this in unmanaged code, and if its a 3dsmax bug submit it to Autodesk.

Also noted down newFace(...) for next build, thanks.
